CHELATIN-SA

CHELATIN-SA | Sugar Acrylate Sequesterants

Product Information

Chelatin-SA is a multifunctional auxiliary developed as an efficient sequestering, dispersing (protective colloid) and chelating agent for all stages in wet processing and dyeing of cellulosic and its blends. It can be also used for pre-treatment with Hydrogen Peroxide as a stabiliser in bleach bath. It has excellent Ca & Fe Chelation values even at pH values of 9-11, hence it is suitable for scouring, bleaching and washing off.

Chelatin-SA is a sugar acrylate polymer with a very good biodegradability. It does not increase the COD/BOD values in the effluent. It shows no demetalizing effect for heavy metal containing dyes, if used in dyebath. It is suitable for both batch as well as continuous process.
